Quick start
From import to result in five steps.
- Choose Image Compression, Image Conversion, or Video Conversion in the sidebar.
- Drop a file, multiple files, or a folder into the processing queue.
- Set quality, output format, codec, resolution, and destination in the inspector.
- Test a small group first, then start the full batch.
- Open the output folder and verify size, quality, format, and playback.
Before processing important files
Keep a backup and test a small group first. Only enable replacement of source files after you have verified the result.
01 · Image compression
Compress images and PDFs
Use this workflow to reduce file size in batches. Import images, PDFs, or folders, then choose quality, metadata handling, destination, and whether to replace originals.
Recommended setup
- Start with the recommended or balanced profile, then adjust after reviewing size and quality.
- Keep metadata when capture details matter; remove it when appropriate for web or sharing.
- PDF is available only in compression and is not an image-conversion output.
PNG · JPEG · GIF · WebP · HEIC/HEIF · TIFF/TIF · PDF
02 · Image conversion
Convert image formats in batches
Convert HEIC, WebP, and other images to broadly compatible JPEG or PNG, or move between other common image formats.
What to check
- Choose an output format, then review quality, alpha-channel, and metadata options.
- JPEG does not support transparency. Choose PNG or another alpha-capable format when transparency matters.
- After conversion, verify the extension, color, and transparent areas.
JPEG · PNG · GIF · BMP · TIFF · WebP · HEIC/HEIF
03 · Video conversion
Convert format, codec, and resolution
Compress video, convert MKV or MOV to MP4, or turn HEVC into broadly compatible H.264.
What to check
- Choose MP4, MOV, M4V, MKV, or AVI, then select H.264 or HEVC where supported.
- Keep the original resolution or choose 4K, 1440p, 1080p, 720p, 480p, 360p, or a custom size.
- Confirm audio handling and play the result on the target device or platform before delivery.
MP4 · MOV · M4V · MKV · AVI · H.264 · HEVC
04 · Results and output
Verify results before organizing source files.
The queue shows each file's status. When processing finishes, open the destination, confirm every file opens or plays correctly, and compare size and quality. If needed, adjust settings and process the original again.
Local processing and network access
Compression and conversion happen locally on Mac. App Store download, purchase validation, restore purchases, update checks, or feedback you submit may require network access.
